Method of calculation Each day is divided into two time periods: Daytime - the period from sunrise to sunset Nighttime - the period from sunset to sunrise. Each period contains eight Choghadiya's. The daytime difference is arrived at by calculating the difference between Sunrise and Sunset and dividing the same by 8. Example Day 1: Sunrise at 6:00 AM and Sunset at 6:01 pm Day 2: Sunrise at 6:00 am based on the above The daytime period is 12 hours and 01 minutes (721 minutes). The nighttime period is 11 hours and 59 minutes (719 minutes). Therefore, each daytime Choghadiya lasts 721/8 = 90.125 minutes = 1 hour 30 minutes 7.5 seconds And each night-time Choghadiya last 719/8 = 89.87 minutes = 1 hour 29 minutes 52.5 second External links https://hinduism.stackexchange.com/questions/26242/how-is-the-first-choghadiya-decided https://astrologyfutureeye.com/astrology-knowledge/choghadiya https://www.thedivineindia.com/choghadiya-muhurat/6953 https://www.thedivineindia.com/aaj-ka-choghadiya-muhurat.html [aaj ka choghadiya muhurat] Hindu astronomy Technical factors of Hindu astrology Hindu calendar
